COOLING, APPARATUS.

Specification of Letters Patent.

Patented Feb. 21, 1911.

Application filed March 25, 1310. Serial No. 551,459.

To all whom it may concern:

Be it known that we, THOMAS HENRY Harms and MARTIN Dmnnnrorr RUCKER, both engineers, subjects of the King of Great Britain, residing at Pretoria VVorks, Bradford, England, and Broad Lanetuary Chambers, lVestminster, London, England, respectively, have invented new and useful Improvements in Condensers, Cooling Ap paratus, Radiators, and the Like, of which the following is a specification.

This invention relates to improvements in condensers, cooling apparatus, radiators and the like, and has for its object to provide a means whereby such apparatus is not only rendered more efficient and economical, but which, owing to its peculiar construct-ion, may be assembled in elements of any desired size and capacity, on the multiple unit principle to suit given conditions, and the said units rendered fluid tight as regards each other by tie rod and single nut at top and bottom common to the series.

In order the better to describe this inven tion reference is made to the accompanying drawings, in which Figure l is a front elevation of an element. Fig. 2 is a side view of Fig. 1. Fig. 3 is a sectional part plan. Fig. 4 shows detail of bush.

In the drawings A is a single element. This element is formed from preferably a single sheet of metal such as aluminium, lead, zinc, tin, coated iron or the like. One half of the sheet is ribbed, channeled, fluted, or corrugated, as shown at 1 is Figs. 1 and 3, while the other half of the sheet is plain as at 2 and folded over against the other and corrugated portion, a joint 3 being formed at the top, bottom and side. 4

We do not limit the invention to a single sheet folded over as it is obvious that two separate sheets may be employed jointed all around, but the method above indicated is more satisfactory, in as much as it saves a joint.

Previous to jointing up the elements socket recesses 4 are formed in both sides of the element at top and bottom, to accommodate bushes B, but after the joint is formed the whole element is cross corrugated as at 5 (Fig. 2).

It is well known that on a plain surface or even with a single corrugated surface water flowing will tend to take a path of least resistance by gravity from inlet to outlet and that once a stream path be formed on the surface of such, surface water will tend to adhere to such path, and a large portion of the surface of any surface condenser therefore be inoperative and useless.

The object of first corrugating the one sheet and then cross corrugating the double sheet is to break up the flow of water and overcome the stream action of gravity b the force of capillarity, the two walls of the elementat cross corrugation being but a very slight distance apart. Further while in cross corrugating it is almost impossible to bring the corrugated surface into such close contact with the plain surface as to stop the flow of water the distance apart of the two sides may be so regulated by the depth of cross corrugation as that any desired rate of flow may he obtained.

The bushes B are formed of metal and have distance pieces or lugs 6 arranged to project both laterally beyond the bush and element and internally as shown in Fig. 4:. The external portion of the lug is adapted to enter the bush of the contiguous element when assembled and the internal portion to preserve the alinement of the tie rod 7, used for jointing up the series as shown in Fig. 2. Each bush is drilled as at 8, so that there be free communication between the interior of the element A and the interior of the bush B.

At the end of the series when assembled a special bond, union, or T piece 9, is employed, having a seating 10, adapted to accommodate the tie rod 7, and its nut 11. In operation the water or other fluid enters the bend 9, and flows along within the series of bushes B, which form when assembled an articulated pipe, a single washer or packing of any suitable material 12 being all that is necessary to form a joint when the elements are tightened up from either end.

The fluid in entering the element is dis tributed at the point of first cross corrugation over the entire width and in small streams that co-mingle at each succeeding point of cross-corrugation, the fluid traverses the entire length of the element until the exit is reached and it flows away. In such manner the maximum cooling surface is pre sented to the medium to be cooled, providing not only an extremely eflicient but very inexpensive and light condenser. Conversely the radiating properties of the apparatus may be utilized for heating, warming, and drying.

We claim- 1. A vessel or element formed of thin sheet metal and having two of its sides arranged at a short distance apart, one only of the said sides having vertical corrugations, and said vertical corrugations being relatively shallow and arranged close adjacent to each other, and both sides having similar horizontal corrugations.

2. A vessel or element formed of thin sheet metal and having two of its sides arranged at a short distance apart, one only of the said sides having vertical corrugations, and said vertical corrugations being relatively shallow and arranged close adjacent to each other, and both sides having similar horizontal corrugations, said sides having also laterally projecting pockets at their upper and lower parts provided with openings.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
